Mass versus period plots showing the surviving simulated planets from the pebble accretion scenario. Marker colour denotes the percentage of solids that is comprised of pebbles. Red markers denote the masses and periods of the observed Trappist-1 planets with error bars (Grimm et al. 2018). Left panel: mass versus period diagram for simulations not including the effects of pebble ablation. Right panel: effects of pebble ablation.
